Reviewers

Sometimes there are some things that are not
allowed in source code. It is the simplest way
to just match those strings by a regular expression.

Like a forbidden or deprecated include in C++ or
just a simple TODO in a comment.

Configured two lines with regex.
Added a file with matching strings and saw that
both regex are found.
